Hi folks,
Was there ever any schematics produced for the SES Robotic Arm? I’ve checked the website, but I can’t see anything obvious…
I’m looking for numerous measurements, and a schematic would be an absolute godsend!
Thanks guys,
Nick
Not sure what you’re asking for here… A schematic of the arm would consist of the electronics not the mechanics. Here is the assembly guide for the closest version of the SES arm we are currently selling. The AL5C-KT
Thanks Jim.
I’ve had a look all through the assembly guides, and they dont go into the level of precision that I’m seeking unfortuantely. Apologises, schematics may be the wrong word.
Blueprints may be a better word. It is the mechanics and the physical dimensions that I’m interested in. I presume that there aren’t any available as they’re not on the website?
I’d be happy to help if you can tell me specifically what you’re interested in.
What I’m particularly interested in is the axis of motion for the shoulder joint.
Looking at the robot, the point around which the base rotates is offset in both X and Y directions. Looking at it from the front (with the grippers facing you, and the SSC32 behind it), the midline of the arm appears to be approximately 40mm offset to the right.
And, if the arm is facing to your left, the axis on which the shoulder joint moves appears to be approximately 25mm to the left.
These measurements are purely from observation, and I was hoping to find a blueprint that showed the base and shoulder joint, so that I can get exact measurements from it.
Any help you can provide is much obligued! I’m writing control software for the arm using an FPGA-based development board, and I need to be as accurate as I can.
Cheers,
Nick
Yes there are some minor offsets. It would be very time consuming for some one to document it. But that’s not the only problem. There is enough mechanical leeway in some of the components when assembled that the only good way is to build it and measure it.
OK, I’ll have to see if I can scrounge a suitable measuring device. A ruler just doesn’t cut it! 
Thanks.
What’s the application that requires such high precision?
Masters project to implement a controller for it based on an FPGA. Error and error tolerance, whilst not all that important to the final application, need analysing in depth in my project write up.
